The way this works is:
  - We only care if the symbol starts with _Z.  Do it in the same
place we check for _Z now, instead of the switch_to_cp_abi call.

  - You just want to call cplus_demangle; be sure to free the result
if it returns non-NULL.

(and yes, stop checking once the ABI is set to v3).
